Did somebody say space laser?
We’re set to launch ICESat-2, our most advanced laser instrument of its kind, into orbit around Earth on Sept. 15. The Ice, Cloud and land Elevation Satellite-2 will make critical observations of how ice sheets, glaciers and sea ice are changing over time, helping us better understand how those changes affect people where they live. Here’s 10 numbers to know about this mission:
One Space Laser
There’s only one scientific instrument on ICESat-2, but it’s a marvel. The Advanced Topographic Laser Altimeter System, or ATLAS, measures height by precisely timing how long it takes individual photons of light from a laser to leave the satellite, bounce off Earth, and return to ICESat-2. Hundreds of people at our Goddard Space Flight Center worked to build this smart-car-sized instrument to exacting requirements so that scientists can measure minute changes in our planet’s ice.

Two Types of Ice
Not all ice is the same. Land ice, like the ice sheets in Greenland and Antarctica, or glaciers dotting the Himalayas, builds up as snow falls over centuries and forms compacted layers. When it melts, it can flow into the ocean and raise sea level. Sea ice, on the other hand, forms when ocean water freezes. It can last for years, or a single winter. When sea ice disappears, there is no effect on sea level (think of a melting ice cube in your drink), but it can change climate and weather patterns far beyond the poles.
3-Dimensional Earth
ICESat-2 will measure elevation to see how much glaciers, sea ice and ice sheets are rising or falling. Our fleet of satellites collect detailed images of our planet that show changes to features like ice sheets and forests, and with ICESat-2’s data, scientists can add the third dimension – height – to those portraits of Earth.
Four Seasons, Four Measurements
ICESat-2’s orbit will make 1,387 unique ground tracks around Earth in 91 days – and then start the same ground pattern again at the beginning. This allows the satellite to measure the same ground tracks four times a year and scientists to see how glaciers and other frozen features change with the seasons – including over winter.
532 Nanometer Wavelength
The ATLAS instrument will measure ice with a laser that shines at 532 nanometers – a bright green on the visible spectrum. When these laser photons return to the satellite, they pass through a series of filters that block any light that’s not exactly at this wavelength. This helps the instrument from being swamped with all the other shades of sunlight naturally reflected from Earth.
Six Laser Beams
While the first ICESat satellite (2003-2009) measured ice with a single laser beam, ICESat-2 splits its laser light into six beams – the better to cover more ground (or ice). The arrangement of the beams into three pairs will also allow scientists to assess the slope of the surface they’re measuring.
Seven Kilometers Per Second
ICESat-2 will zoom above the planet at 7 km per second (4.3 miles per second), completing an orbit around Earth in 90 minutes. The orbits have been set to converge at the 88-degree latitude lines around the poles, to focus the data coverage in the region where scientists expect to see the most change.
800-Picosecond Precision
All of those height measurements come from timing the individual laser photons on their 600-mile roundtrip between the satellite and Earth’s surface – a journey that is timed to within 800 picoseconds. That’s a precision of nearly a billionth of a second. Our engineers had to custom build a stopwatch-like device, because no existing timers fit the strict requirements.
Nine Years of Operation IceBridge
As ICESat-2 measures the poles, it adds to our record of ice heights that started with the first ICESat and continued with Operation IceBridge, an airborne mission that has been flying over the Arctic and Antarctic for nine years. The campaign, which bridges the gap between the two satellite missions, has flown since 2009, taking height measurements and documenting the changing ice.
10,000 Pulses a Second
ICESat-2’s laser will fire 10,000 times in one second. The original ICESat fired 40 times a second. More pulses mean more height data. If ICESat-2 flew over a football field, it would take 130 measurements between end zones; its predecessor, on the other hand, would have taken one measurement in each end zone.
And One Bonus Number: 300 Trillion
Each laser pulse ICESat-2 fires contains about 300 trillion photons! Again, the laser instrument is so precise that it can time how long it takes individual photons to return to the satellite to within one billionth of a second.

DRYP - an app that keeps your plants alive and happy
Hi Tumblr!
I know I’ve been gone for a while.
In part it’s because I’ve been working on an app!
I keep a lot of plants. I think everyone should!
- They clean your air - They give you something to name - They give you something to take care of - They teach you about care, needs, and resources - They make you look like you’re good at decorating
Here are some of mine:
But some people, because they’re overwhelmed or simply can’t figure out how to start, think that plants are out of their reach.
DRYP is for newcomers and experts.
It reminds you when to water
And it helps you fix what’s broken
If you think the world would be better with this app in it, please consider contributing to the Kickstarter!
I’ve tried to make it worth your while:
Again here’s the link to contribute:
DRYP - an app that keeps your plants alive and happy
And if you like me / if you like my idea, please signal boost!

signs in midheaven
aries MC: hardworking and ambitious, these people have a set path or goal they have in mind and they will achieve it no matter what. sometimes they can be more shy in their daily life, but it’s important for them to shine and be the very best in their work. they need balance because they may switch wildly from one thing to another and be very rash in their decision making. they are very creative and can brainstorm great ideas.
taurus MC: as per usual with taurus placements, this placement doesn’t like change. they are stubborn and will stick with a career or thought process even if it’s terrible for them. they are stubborn and persistent people who love to help others. an ideal career path for them would be something where they create and are hands-on. they need to be able to see the process and see the fruits of their labors.
gemini MC: gemini’s are known for their creativity, but they can become easily burnt out and need time to recharge. they can also become easily bored, so a career or lifestyle that is exciting with many different tasks is essential for them. these are curious people who are in love with learning new things and improving themselves. gemini’s have a great sense of aesthetics and are great with detail oriented things, so a career that combines these would be ideal.
cancer MC: sweet, trustworthy people who are great at teaching others. change is, again, difficult but they can become ambitious if they find a specific thing they love to do. a job that can bring about fame and responsiblility would be great for them. an amazing intuition will benefit them in any career dealing with people, where they will thrive. they are born planners and need to feel respected for all the work and nurturing they do.
leo MC: leo’s are known for their ambition and wild dreams, and they can achieve these dreams because they are persistent and tenacious people. they are very organized and extremely generous. they can tend to be petty if they feel personally persecuted and completely give up on something though. good in a crisis, they definitely need to be applauded for their efforts in whatever career path they are in. they enjoy being in the public eye as long as they are loved. their ego can either be an asset or a hindrance if they are not developed.
virgo MC: so naturally critical it can get annoying lol. they are great with language, research, and even teaching. when they commit, they will take everything very seriously. they like to play it safe, taking a job that they know will grant them stability, but they need something that will let them live up to their full potential. they always see the big picture. a workspace that is free of chaos is essential. they tend to over analyze things, which can turn into indecisiveness in the eyes of others.
libra MC: great coworkers who listen as well as input ideas. they are able to climb the ladder because they’re strong communicators and work well with others. they are flexible, and who you definitely want to work with you in a team setting. they love to mentor others and push others to success. their downside is they tend to stay in a box rather than break out on their own with their own ideas when they don’t have sufficient confidence. if there’s a problem at home, they will bring it to work, and vice versa.
scorpio MC: those with scorpio in midheaven are no strangers to transformation, so it is likely that they will change their profession a few times. although easily frustrated, they are smart enough to chase their dreams until they succeed. these are very smart people, but they can let their emotions get the better of them, so it is essential that they balance their intellect and strong emotions. they don’t like being subordinates, so these people make good leaders and bosses. they need a career they are extremely passionate about to be able to be happy.
sagittarius MC : this placement also is in love with learning, and will continue to do this throughout their life. they adore a challenge, and a good argument. they need a career that will grant them independence and one where they will be able to plan and prepare. they want to be able to impart their great knowledge and opinions onto others. they might change professions a few times, despite appearing stubborn and stuck in their ways. this placement is always focused on the future, when they need to look at their present situation.
capricorn MC: confident and patient. people instantly trust in this placement. it’s important for them to have a set goal. they have a sense of duty that coexists with their need to care for others, like cancer midheaven. structure is essential, a corporate ladder would be perfect. they garner respect from everyone, so they make natural leaders. a lot of pressure is put on this placement, so they can become bitter. their ultimate goal is to achieve complete stability and success in their given profession. these are practical people who can bottle up their true feelings.
aquarius MC: these people are afraid of looking uneducated in front of others, so they will research into something until they know absolutely everything about it. they are flexible and creative in their problem-solving. although they are great at doing their own thing, they’re even better in a team setting. they want to help the world, jobs that are nontraditional and highly specialized are perfect. can come off as arrogant because they feel they are the smartest/best at their job.
pisces MC: because of their idealism, they have a hard time choosing what they want to do with their life. they may have to hit rock bottom before realizing their true path. they get overwhelmed easily when met with many challenges at once, but they are creative enough to solve all their problems if they have time alone to think. decisions are based on emotions and their natural intuition. they are not usually the first to make a move.
