Cancelled Missions: Testing Shuttle Manipulator Arms During Earth-Orbital Apollo Missions (1971-1972)

In this drawing by NASA engineer Caldwell Johnson, twin human-like Space Shuttle robot arms with human-like hands deploy from the Apollo Command and Service Module (CSM) Scientific Instrument Module (SIM) Bay to grip the derelict Skylab space station.

"Caldwell Johnson, co-holder with Maxime Faget of the Mercury space capsule patent, was chief of the Spacecraft Design Division at the NASA Manned Spacecraft Center (MSC) in Houston, Texas, when he proposed that astronauts test prototype Space Shuttle manipulator arms and end effectors during Apollo Command and Service Module (CSM) missions in Earth orbit. In a February 1971 memorandum to Faget, NASA MSC's director of Engineering and Development, Johnson described the manipulator test mission as a worthwhile alternative to the Earth survey, space rescue, and joint U.S./Soviet CSM missions then under study.

At the time Johnson proposed the Shuttle manipulator arm test, three of the original 10 planned Apollo lunar landing missions had been cancelled, the second Skylab space station (Skylab B) appeared increasingly unlikely to reach orbit, and the Space Shuttle had not yet been formally approved. NASA managers foresaw that the Apollo and Skylab mission cancellations would leave them with surplus Apollo spacecraft and Saturn rockets after the last mission to Skylab A. They sought low-cost Earth-orbital missions that would put the surplus hardware to good use and fill the multi-year gap in U.S. piloted missions expected to occur in the mid-to-late 1970s.

Johnson envisioned Shuttle manipulators capable of bending and gripping much as do human arms and hands, thus enabling them to hold onto virtually anything. He suggested that a pair of prototype arms be mounted in a CSM Scientific Instrument Module (SIM) Bay, and that the CSM "pretend to be a Shuttle" during rendezvous operations with the derelict Skylab space station.

The CSM's three-man crew could, he told Faget, use the manipulators to grip and move Skylab. They might also use them to demonstrate a space rescue, capture an 'errant satellite,' or remove film from SIM Bay cameras and pass it to the astronauts through a special airlock installed in place of the docking unit in the CSM's nose.

Faget enthusiastically received Johnson's proposal (he penned 'Yes! This is great' on his copy of the February 1971 memo). The proposal generated less enthusiasm elsewhere, however.

Undaunted, Johnson proposed in May 1972 that Shuttle manipulator hardware replace Earth resources instruments that had been dropped for lack of funds from the planned U.S.-Soviet Apollo-Soyuz Test Project (ASTP) mission. President Richard Nixon had called on NASA to develop the Space Shuttle just four months before (January 1972). Johnson asked Faget for permission to perform 'a brief technical and programmatic feasibility study' of the concept, and Faget gave him permission to prepare a presentation for Aaron Cohen, manager of the newly created Space Shuttle Program Office at MSC.

In his June 1972 presentation to Cohen, Johnson declared that '[c]argo handling by manipulators is a key element of the Shuttle concept.' He noted that CSM-111, the spacecraft tagged for the ASTP mission, would have no SIM Bay in its drum-shaped Service Module (SM), and suggested that a single 28-foot-long Shuttle manipulator arm could be mounted near the Service Propulsion System (SPS) main engine in place of the lunar Apollo S-band high-gain antenna, which would not be required during Earth-orbital missions.

During ascent to orbit, the manipulator would ride folded beneath the CSM near the ASTP Docking Module (DM) within the streamlined Spacecraft Launch Adapter. During SPS burns, the astronauts would stabilize the manipulator so that acceleration would not damage it by commanding it to grip a handle installed on the SM near the base of the CSM's conical Command Module (CM).

Johnson had by this time mostly dropped the concept of an all-purpose human hand-like 'end effector' for the manipulator; he informed Cohen that the end effector design was 'undetermined.' The Shuttle manipulator demonstration would take place after CSM-111 had undocked from the Soviet Soyuz spacecraft and moved away to perform independent maneuvers and experiments.

The astronauts in the CSM would first use a TV camera mounted on the arm's wrist to inspect the CSM and DM, then would use the end effector to manipulate 'some device' on the DM. They would then command the end effector to grip a handle on the DM, undock the DM from the CSM, and use the manipulator to redock the DM to the CSM. Finally, they would undock the DM and repeatedly capture it with the manipulator.

Caldwell Johnson's depiction of a prototype Shuttle manipulator arm with a hand-like end effector. The manipulator grasps the Docking Module meant to link U.S. Apollo and Soviet Soyuz spacecraft in Earth orbit during the Apollo-Soyuz Test Project (ASTP) mission.

Johnson estimated that new hardware for the ASTP Shuttle manipulator demonstration would add 168 pounds (76.2 kilograms) to the CM and 553 pounds (250.8 kilograms) to the SM. He expected that concept studies and pre-design would be completed in January 1973. Detail design would commence in October 1972 and be completed by 1 July 1973, at which time CSM-111 would undergo modification for the manipulator demonstration.

Johnson envisioned that MSC would build two manipulators in house. The first, for testing and training, would be completed in January 1974. The flight unit would be completed in May 1974, tested and checked out by August 1974, and launched into orbit attached to CSM-111 in July 1975. Johnson optimistically placed the cost of the manipulator arm demonstration at just $25 million.

CSM-111, the last Apollo spacecraft to fly, reached Earth orbit on schedule on 15 July 1975. By then, Caldwell Johnson had retired from NASA. CSM-111 carried no manipulator arm; the tests Johnson had proposed had been judged to be unnecessary.

That same month, the U.S. space agency, short on funds, invited Canada to develop and build the Shuttle manipulator arm. The Remote Manipulator System — also called the Canadarm — first reached orbit on board the Space Shuttle Columbia during STS-2, the second flight of the Shuttle program, on 12 November 1981."

Antenna — S-T (Urge)

Royal Headache had a close to decade-long run, but it was never easy. They went from dive bar shows to opening for the Black Keys within only a few years and flamed out finally in 2017, as substance abuse and interpersonal disputes took their toll. And yet, if you like your punk rock spiked with romantic tunefulness, if you harbor affection for the Buzzcocks, the Jam or, further back, the Small Faces, there just weren’t any other bands like Royal Headache. A lot of that was due to one Tim “Shogun” Wall, vocally a dead ringer for a young Rod Stewart, but scrawny, amped to the gills, grappling with the mic and stalking the stage floor, making an anthemic, super-charged racket.

Interviews suggest that Royal Headache’s rapid rise and fall left Shogun in a pretty nasty place, but now, half a decade later with Antenna, he’s back at it, making music again. We covered Finnogun’s Wake, his duo with Finn Berzin in the first Dust of 2024. Andrew Forell placed it, “somewhere between the concise attack of Shogun’s former band Royal Headache and the anthemic end of Britpop.” This five-song EP from Antenna runs faster and more punk than the last Royal Headache album, and it’s, thankfully, not as indebted to Blur/Oasis and their ilk. It’s better than Finnoguns Wake then, and as good or maybe even better than the two Royal Headache records.

“Cube,” for instance, rages headlong, double-time, in a fury of drum-bass-guitar flailing. It’s fast but precise—Shogun has put together a very capable band here—and it feels like it might fly apart at any moment but doesn’t. But where most bands operating at this pace and volume might content themselves with shouted lyrics, Shogun puts frill and ornament into the singing, nailing the tune and ending phrases in lavish, multi-toned flourishes. It’s like Tom Jones finding himself in front of Bad Brains, and it’s fun.

“English Three” bangs just as hard, slamming the one-two beat with a jackhammer intensity. Musically, it’s got an antsy, carnival glee vibe, which contrasts with the lyrics, which deal with mid-life alienation and isolation. “Don’t own me, touch me, I don’t need anybody, until the ending of the day,” declares Shogun. By the sound, you’d think it’s a stirring manifesto, but the words are more like a suicide note.

The EP ends in glory, with the seething, soaring, blue-eyed soul anthem “Antenna State,” hemmed in by with flaring guitars and Motown-style backing “oohs and ohs.” “Don’t smoke god, don’t smoke god, love should be all that you need,” wails the singer, in fluid, florid dramatics that would carry to the back rows of even the largest venues Royal Headache used to play. Maybe we don’t need religion or drugs to feel this good, but we sure do require quality rock and roll.

5G technology features in brief. Speed ​​up to 10 Gbits.

Great app

100 times more device connections

Fast response time

Waste of time

Another software option to upgrade. Great potential

With the proliferation of digital around the world, when live streaming and games, sports, news, movie reviews, social media, etc., the transfer of large amounts of data from one host to another and the Internet of Things (IoT) spurred the development of mobile phone standards. .

However, the 5G technology network has not yet reached its potential because the existing devices and infrastructure are not yet ready to support the 5G technology network. Those who have tested the 5G technology network using it with built-in 4G devices in this application are also called non-stationary 5G technology networks. The full potential of 5G technology will only be realized when independent networks, compatible devices and better communication tower technologies become available.

Advantages of 5G technology

Transfer data faster

The previous generation 4G LTE technology used bands below 3 GHz but in comparison, 5G technology uses bandwidth from 6 GHz in length to 24 GHz. However, it is important to note that 5G technology coverage also requires a base station and a broadcast tower compared to a 4G data network.

Improved network

5G networks are more flexible as they work with different customers, services and market segments. It divides its network in such a way that it will adapt to the needs of the users. It is based on Network Functions Virtualization (NFV) and Software Defined Networking (SDN). It is also called a "network fragment". This provides high data rates, low power consumption, and reliable low latency.

Moving Beamforming

Moving Beamforming refers to a radio signal processing technique that allows for the transmission or reception of a directional network, unlike a passive antenna that beams the signal randomly in all directions. 4G networks also use beamforming to some capacity, but in a growing sense.

Benefits for companies and businesses

It provides improved machine-to-machine communication for automation, real-time communication and guaranteed network availability, digitization of healthcare and agricultural industries.

Benefits for consumers

It provides fast download and download times when you are streaming users. Stable connection to mobile communications, low response time for online or cloud gaming, virtual reality, high quality live TV and 4K video telephony.

A more secure network

5G technology networks offer more security than previous generation networks. It supports protection against data loss, data corruption and theft. The exchange of sensitive and private customer data, such as hospital patient reports, customer data and student information at universities, is more secure in the 5G technology network.

Disadvantages of 5G

Limit coverage

The 5G technology network is a new technology, it requires a large network of ports and transmission towers worldwide, which requires a lot of time, testing, testing and setting up 5G technology towers.

Reduces durability

If the experts are to be believed, the non-standard 5G technology network undermines the performance of 4G network devices. Although a few manufacturers have started to produce 5G technology network devices, R & D believes that due to high data transmission in the largest network, the longevity or service life of mobile phones and other devices will be compromised.

Involvement in aviation

In January, Air India cancled several flights to the United States because they were rolling out 5G technology services in the country. This is a major setback of 5G technology in India as airlines have suffered losses due to ongoing 5G technology deployment projects. It can also be a hindrance in the future if not dealt with quickly. Internet Security Threats

Although the 5G technology network is said to help improve cybersecurity, it also has its limitations as it encourages cloud computing and exposes more data to risk. of hacking due to its lack of privacy and ease of access to network networks. on the other hand. hands

5G technologyin India

India officially launched its 5G technology network in October this year at an event held in New Delhi. Airtel and Jio have started rolling out 5G technology data plans in select state. However, Vodafone Idea is not planning to launch it in the near future.

In case of Airtel, they are currently placed in Tier I to Tier 8 countries. Jio has launched 5G technology services in limited areas. Many telecom operators are also of the opinion that pan-India 5G technology network coverage will take a few years. Jio recently announced after the 5G technology beta test that no SIM card is required to operate Jio's 5G technology network. However, Vodafone Idea has not yet announced its 5G technology network.

The health risks of 5G technology and the disadvantages of 5G technology for the environment

The International Commission on Non-ionizing Radiation Protection (ICNIRP) has stated that increasing radio frequencies above 6 GHz may have biological and health effects. The 5G technology network will increase the amount of electromagnetic radiation in the environment, causing a greater risk of cancer. With the lack of power of 5G technology network devices, there will also be an increase in the collection of electronic waste. The electric current from the cell tower exposed sparrows and other birds to increased egg production and nesting behavior. High rates of energy consumption have also contributed to global warming.

one of the really interesting things about ham radio so far has been how jarring it is compared to normal consumer experiences

what I mean is - all the consumer radio products we use are, well, consumer products. they've had all the rough edges sanded off. your FM stations come in great, bluetooth shit Just Werks. Yeah you'll run into static or get too far away from a station, or maybe your bluetooth adapter is drowned out or hits weird reflections or something. but for the most part this shit is just, you grab it off the shelf and plug it in and go. and it's not like that at all when you start getting into the actual hardware.

there is an INCREDIBLE websdr project out of a Georgia school that uses a fan dipole and a high end sdr that can sample basically the whole ham spectrum at once. like seriously you should hang out there, it's a really fucking cool tool. but just like consumer radio products, it's almost... TOO good. it gives you a somewhat misleading picture of what's possible. most people don't have the space, money, or time to set up and maintain a big multi-band antenna and also give the world access to it for free.

so like. when you actually get beyond poking around SDR servers, what i've quickly learned is that actually there's real limits to what's possible. There's monetary ones (if you want a big fancy radio setup you either make it yourself or you pay OUT THE FUCKING ASS) but there's also practical ones.

Handheld units will do the really high frequencies but physics and practical reality mean you can't have a handheld transceiver that covers below like... i think 6m? Some of them can receive at lower frequencies than that but they won't transmit. You can't safely put enough power for that into a handheld unit without frying the user and the antenna on a handheld is too small.

Many of the radios on the market are band-dedicated. it's just easier that way. some of them will do multi-band stuff but the more it does, the more expensive it is.

and that's not even getting into broadcast modes. if you're buying a handheld it's probably just FM or AM/FM. you can buy a more stationary radio unit but even that might not do all bands.

anyway. rambling over. it's just weird to switch from thinking of radio as a perfected thing that's in every car as an afterthought, to thinking of it as an imperfect or constrained process of communication.

Designing antennas for such confined spaces is difficult, but with the correct skills and knowledge, engineers may create efficient antennas for small devices. This article discusses the key elements, methodologies, and technology for developing small RF antennas.

1. Understand the requirements.

Before beginning the design, it's critical to define:

Frequency range: Which band(s) should the antenna cover.

Applications include cellular, WiFi, IoT, Bluetooth, and GPS.

Size limitations refer to the physical dimensions of the device.

Radiation pattern: omnidirectional or directed.

Efficiency: A trade-off between size and performance.

2. Design Challenges for Small RF Antennas.

Proximity Effects: Nearby components and housing can cause the antenna to become detuned.

Bandwidth Limitations: Compact antennas frequently have a narrow bandwidth.

Integration Issues: The antenna must not interact with other components.

3. Important Techniques for Designing Compact RF Antennas

a) Miniaturization techniques

Meander Line Antennas: Folding the conductive route in a zigzag or meandering pattern to minimize the antenna's footprint.

Planar inverted-F antennas (PIFA): PIFA antennas, which are commonly used in compact devices, give high efficiency in a short space.

Helical Antennas: Winding the antenna wire into a helix shortens its length while retaining resonance.

Dielectric loading: Using materials with a high dielectric constant minimizes the antenna's physical size.

b) Matching and tuning.

Compact antennas frequently require matching networks (e.g., inductors, capacitors) to achieve impedance matching with the RF circuitry, hence increasing power transmission and efficiency.

c) Multi-band and wideband designs.

Slots and Notches: Adding slots or notches to the antenna design can enable multi-band operation.

Fractal Geometry: Using self-repeating patterns allows for wideband or multi-band designs in a compact shape.

d) Advanced Substrates and Materials. Flexible substrates are ideal for wearable applications.

Use Low Temperature Co-fired Ceramics (LTCC) to create compact layered patterns.

4. Simulation and Optimization.

Simulation tools like Advanced Design System (ADS), CST Studio, or HFSS can help with:

Visualizing the radiation pattern and impedance.

Optimizing parameters such as gain, bandwidth, and size.

Predicting how close components impact performance.

5. Prototypes and Testing

Prototyping options include PCB etching, 3D printing, and commercial fabrication services.

Test parameters like as return loss (S11), radiation efficiency, and gain in an anechoic chamber.

Tuning: Change the design or matching network based on test findings.

6. Practical Tips for Compact Antenna Design

Utilize Device Edges: Place antennas along the PCB's edges or corners.

Consider the ground plane: Its size and shape have a substantial impact on performance.

Antenna Isolation: To avoid interference, ensure enough separation or shielding between antennas and other RF components.

Use Embedded Antennas: Printed or chip antennas save space while still providing performance.

7. New Trends in Compact Antenna Design

Metamaterials are artificial materials designed to alter electromagnetic waves, allowing for ultra-compact architectures.

On-Chip Antennas: Antennas are integrated directly onto semiconductor chips for high-frequency applications like as 5G.

Energy Harvesting Antennas are designs that combine RF energy harvesting and communication.

Conclusion

Designing compact RF antennas for small devices necessitates striking a compromise between size, performance, and application requirements. Engineers can overcome space limits by utilizing downsizing techniques, sophisticated materials, and simulation tools to create efficient antennas adapted to modern compact gadgets.

Eteily Technologies, a pioneer in RF antenna fabrication, can provide tailored solutions for industries such as IoT, automotive, and telecoms.
