Meet UNOOSA and COPUOS at UNHQ.

Right after the Soviet Union launched Sputnik in 1957, UNOOSA, the UN Office for Outer Space Affairs, was established and has since been monitoring developments across more than 77 successful lunar missions as well as other journeys into space. These days, the UN space agency is getting ready to host the UN Conference on Sustainable Lunar Activities in Vienna in June.

Watch UNOOSA’s latest youth competition winners here.

In 1959, the General Assembly created a committee to govern the exploration and use of space for the benefit of all humanity for peace, security and development.

Instrumental in creating the five treaties and five principles of outer space, the Committee on the Peaceful Uses of Outer Space (COPUOS) has mandated duties that include keeping pace with rapid advances in space technology.

It's October 4th, the beginning of 🔭 World Space Week. The World Space Week Association (WSWA) sponsored the first “Spaceweek” in 1980 as a celebration of the first Moon Landing. From the very beginning of the Space Age, the United Nations (UN) recognized that outer space adds a new dimension to our existence. In 1999, the UN officially declared 04-10 October of every year as “World Space Week” to celebrate the contributions of space science and technology to the betterment of the human condition. 

Space science and technology and their applications are increasingly being used to support a wide range of UN activities. At least 25 UN entities and the World Bank routinely use space applications to make important and sometimes essential contributions to the achievement of the UN’s Sustainable Development Goals (SDGs). Of the SDG’s 169 target objectives, 65 directly benefit from Earth observation satellites and related technologies.

Space exploration and space-based Earth observation are helping to drive positive change for our planet by identifying land, air, and water pollution levels; monitoring deforestation activities; measuring climate change effects; and supporting agriculture in developing nations to name a few. Beam me up, Scotty! ☮️ Live long and prosper… Jamiese of Pixoplanet

Hi 👋🏼

apologies if you've answered this before but what exactly is your job? cause it sounds fun af!

usually i just say i work in space law but you did ask what exactly my job is so: i am in the space diplomacy department of my country's government working on space sustainability law and policy. and i know what you're thinking: that's a bunch of words! let me explain.

basically, the united nations have a special body dedicated to regulating outer space exploration with the very short and snappy name committee for the peaceful use of outer space (COPUOS). it meets three times a year in vienna, and discusses everything from space trash to moon mining to satellite signals to launching rockets. and i work for one delegation to that committee! my main task is looking at how space technology can be used to improve life on earth and further sustainable development, and how international and national policy decisions can make this use of space more effective. if you want to know more about how exactly that looks like, the united nations office for outer space affairs (UNOOSA) has a website dedicated to the topic:

Space4SDGs!

so basically, i work in space which is cool as fuck, but i do paperwork which most people would consider the lamest kind of space work but don't be fooled! it's the coolest fucking paperwork there is

国連宇宙局（UNOOSA）によれば、2024年6月11日の時点で、11,780基の人工衛星が地球を周回しているという。そのほとんどは機能しており、低軌道に集中している。 　宇宙はもはや人類にとって必須のインフラだ。私たちの頭上を飛び交う人工衛星は、通信からGPS、天気予報や氷の監視にいたるまで、さまざまな役割を果たし、人々の暮らしを支えている。 　そのため、人工衛星の数はここ数年で急増しており、一部のインターネットプロバイダーが引越しを検討するほど混雑しつつあるそうだ。 広告 静止軌道・中軌道・低軌道にある人工衛星 　一口に地球の軌道といっても、いくつか種類がある。 ・静止軌道 　1つは、「静止軌道」と呼ばれるもので、地球の赤道から35,786kmの上空にある。ここに打ち上げられた人工衛星は、地球の自転とピッタリ同じ速度で地球をぐるぐると周るため、地上からは上空で静止しているかのように見える。 　現在、ここには552基の衛星があり、その多くは通信衛星や気象衛星だ。 ・中軌道 　次に、地球上から2,000km～静止軌道までの範囲を「中軌道」という。ここは米国の「GPS」、EUの「ガリレオ」、ロシアの「GLONASS」、中国の「北斗」といった衛星測位システムを支える衛星などが利用する。 　中軌道には現時点で199基の人工衛星があるが、一部の宇宙インターネット・プロバイダーはここの軌道への引越しを検討しているという。というのも、そのさらに下にある「低軌道」が混雑してきているからだ。 ・低軌道 　低軌道は地球上から200km～中軌道までの範囲を指す。現在、低軌道には8,110基の衛星が存在するが、うち6,050基がスペースX社が運用する「スターリンク」のためのものだ。そう、ある意味、この混雑はイーロン・マスク氏が作り出したと言える。 　だがマスク氏はこれに満足しておらず、現在の2倍の12,000基近くを目標としており、さらに3万4400基まで増加させる可能性もある。 3 スターリンク、60基の衛星の打ち上げ（母機分離前） / image credit: Official SpaceX Photos / WIKI commons 地球の低軌道に衛星が大量にあることの懸念 　宇宙は無限に広がっているとはいえ、これほど多くの衛星がとりわけ低軌道に集中することに懸念がないわけでもない。 　1つは、その光によって夜空が変化する恐れがあることだ。 　過剰な光による悪影響を「光害」という。その主な原因は地上の都市の照明で、そのせいで星空が見えなくなるだけでなく、生態系への影響も出ている。果たして、ひしめき合う人工衛星の光は地球にどのような影響を与えるだろうか？ 　もう1つの懸念は、宇宙ゴミの激増だ。人工衛星が効果的に働くことができる軌道は限られており、そのためにルートが交差し、それを再調整するといったことが頻繁に行われている。 　現時点で深刻な事故は起きていないが、今後もっと人工衛星の数が増え続ければどうだろうか？ 　人工衛星もいずれは寿命を終え、機能しなくなるし、そうなってしまえばその制御は容易ではない。 　一度の衝突事故は、その破片を散らばらせ、さらなる衝突へとつながる。 　こうして連鎖的に衝突が起きることを「ケスラー・シンドローム」というが、そうなれば宇宙は使用できない場所となってしまう。 　これから本格的な宇宙時代を迎えようというのに、人類は地球に閉じ込められてしまうかもしれないのだ。

Bolivia’s hypergravity blood cell test for astronaut health

Bolivia’s hypergravity blood cell test for astronaut health. An all-female team from Bolivia is the latest international group to use ESA's hypergravity-generating Large Diameter Centrifuge, with access sponsored by the United Nations and ESA. The researchers are looking into whether the high gravity levels experienced during rocket launches contribute to the anemia that many astronauts suffer from in space. Based at ESA’s ESTEC technical canter in the Netherlands, the LDC is an 8-meter-diameter, four-arm centrifuge that gives researchers access to a range of hypergravity up to 20 times Earth gravity for weeks or months at a time. Access to the LDC was arranged through HyperGES, part of the Access to Space for All initiative sponsored by ESA and the United Nations Office of Outer Space Affairs, UNOOSA. At its fastest, the centrifuge rotates at up to 67 revs per minute, with its six gondolas placed at different points along its arms weighing in at 130 kg, and each capable of accommodating 80 kg of payload. ESA's Large Diameter Centrifuge The five-strong all-female team from Universidad Católica Boliviana ‘San Pablo’ in La Paz, Bolivia, have spent two weeks studying the effects of hypergravity on red blood cells. Astronauts are known to experience numerous adverse health effects while in space. Among them – observed since the earliest days of orbital flight – is anemia, which can cause dizziness and weakness. Recent research shows this anemia is linked to ‘hemolysis'—in’ – in plain words that red blood cells are destroyed at a much higher rate than the usual recycling of old and damaged cells. This finding became the starting point for the team’s research. Preparing_samples_for_testing Team leader Dr. Georgina Chávez explains: “As part of a biology class I assigned a very simple task which many people might do in school: testing how osmosis affects red blood cells. By putting low-salinity ‘hypotonic’ solution in the fluid surrounding the red blood cells, then water moves into the cells and they eventually burst. We saw the paper in Nature on the hemolytic anemia suffered by astronauts, and the parallels with our testing raised our interest. It is possible that hypergravity exposure causes cellular membranes to become fragile, leading to hemolysis. Red_blood_cells_undergoing_hemolysis_after_hypergravity_exposure “What is well known is that the distribution of body fluid changes in weightlessness, so this might promote the same kind of destruction of red blood cells. But most of the existing studies have been done in microgravity. We thought, well actually astronauts go through two big bodily changes during spaceflight: to make it into microgravity they first experience a brief but intense period of hypergravity. So we decided to investigate the effects that this initial phase might have in terms of leading to hemolysis in space later.” Samples_placed_in_LDC For hypergravity testing the team prepared various levels of hypotonic solutions to perform ‘osmotic fragility testing’ on samples that were exposed to 7.5 and 15 Earth gravities as well as normal gravity as a control. The hypergravity spins continue for differing test periods of 10 minutes, 30 minutes and 60 minutes, with samples stored at temperatures of 25°C and body temperature. “It typically takes a few minutes of high-gravity rocket flight to make it into orbit,” notes team member Daira Quenta. “We want to see how the amount of time spent in hypergravity might make a difference.” Hypergravity_centrifuge_in_motion The team had been inspired by previous Bolivian participation in other UNOOSA programs, notably the DropTES (Drop Tower Experiment Series) which enables international researchers to utilize the ZARM drop tower in Bremen, Germany, with a 146-m shaft for brief microgravity testing. “We made the connection – if they can do it, we can do it. The opportunity got us motivated.” Team member Marcia Carrasco comments “We’re training to become biochemistry and bioprocess engineers, which is really quite vocational,” explains team member Belen Flores. “This career encompasses a wide range of options, we might for instance end up working for the pharmaceuticals sector or food companies. We don’t typically have the chance undertake scientific investigations like this, so this has been exciting.” “We are an all-female team, which wasn’t intentional, but they are all brilliant students, and it’s fair to say females are a bit more organised!” Dr. Chavez adds “We didn’t think too much about gender at the time, but we have been part of some important initiatives subsequently, including Matilda, an organisation encouraging female Latin America students to go into STEM subjects. And we’ve been featured on Pica, which is a popular TV show for Bolivian teenagers, raising a lot of interest.” Team member Natalia Agramont says Source: ESA Read the full article

Have you ever stopped to think about what happens to all the objects we send into space? Once they fulfill their purpose, they don't just disappear. Instead, they become part of the growing problem of space debris, commonly referred to as "space kachra".

Space kachra is a serious issue that has gained attention in recent years. It refers to the thousands of defunct satellites, spent rocket boosters, and other debris that orbit our planet. With the increasing number of space missions and satellite launches, the amount of space kachra has reached alarming levels.

One of the main concerns associated with space debris is the possibility of collisions. Even the smallest piece of debris, traveling at high speeds, can cause significant damage to functioning satellites or even the International Space Station (ISS). These collisions can create a chain reaction, where the collision disperses more debris, increasing the risk of further collisions. This phenomenon is known as the "Kessler syndrome" and could potentially render space orbits unusable in the future.

To tackle this issue, space agencies and organizations are actively working on solutions. One approach is to develop technologies that actively remove space debris from orbit. Various methods are being explored, such as using robotic arms, nets, or harpoons to capture and deorbit the debris. Another proposed solution is to design satellites and rockets in a way that ensures they either burn up in the Earth's atmosphere or are safely guided to a designated graveyard orbit at the end of their missions.

International cooperation is crucial in addressing the problem of space kachra. The United Nations Office for Outer Space Affairs (UNOOSA) has been facilitating discussions among different countries to establish guidelines and best practices for the mitigation of space debris. These guidelines aim to ensure responsible space activities, including the removal of debris and prevention of new debris creation.

In addition to the technological and regulatory efforts, awareness and education play a significant role in addressing the issue of space kachra. It is essential for the general public to understand the importance of responsible space activities and how their actions can contribute to mitigating space debris. Encouraging sustainability and environmentally friendly practices in space exploration will be crucial for preserving the future usability of space orbits.

As we venture further into space and rely more on satellite technology, tackling the problem of space kachra becomes even more imperative. With concerted efforts from space agencies, organizations, and individuals, we can ensure that our exploration of space remains sustainable and free from the hazards of space debris. Let us strive to keep our celestial neighborhood clean and ensure a brighter future for space exploration.

The United Nations recognized from the very beginning of the Space Age that outer space added a new dimension to human existence. The family of the United Nations works ceaselessly to utilize the unique benefits of outer space for the benefit of all humanity.

The General Assembly adopted its first resolution pertaining to outer space, resolution 1348 (XIII) titled "Question of the Peaceful Use of Outer Space", in recognition of humanity's shared interest in the cosmos and in an effort to answer questions about how outer space can benefit Earth's inhabitants.

The "Magna Carta of Space", also known as the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies, entered into force on October 10, 1967.

Today, the United Nations Office for Outer Space Affairs (UNOOSA) promotes international cooperation in the peaceful use of outer space. UNOOSA serves as the secretariat for the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), the only committee of the General Assembly dealing exclusively with international cooperation in the peaceful uses of outer space.

UNOOSA is also accountable for carrying out the Secretary-General's responsibilities under international space law and maintaining the United Nations Register of Objects Launched into Outer Space.
