Space, in brief

India's space agency ISRO said on Sunday it will "neither be privatised nor will its importance be diminished". [1]

The statement answered a letter of 4 September from ISRO's own staff association, which asked chairman V. Narayanan about reports that manufacturing and operational work is being moved to companies. [1]

Staff also said the Department of Space, India's government department that oversees ISRO, had sent them no formal communication about any of it. [1]

ISRO named what it is keeping: advanced space research and technology development, national and strategic missions, space science and exploration, and critical and frontier space capabilities. [1]

Routine rocket production is not on that list, and it has already gone. A consortium led by Hindustan Aeronautics and Larsen and Toubro now produces the Polar Satellite Launch Vehicle, India's most-flown launcher. [1]

India's government has also handed Hindustan Aeronautics the technology for the Small Satellite Launch Vehicle, a smaller rocket for small payloads. [1]

Pawan Goenka, who chairs India's space regulator IN-SPACe, said ISRO's role "is by no means diminishing" and called it the bedrock of the sector. [1]

India opened its space sector to private companies in 2020 under Prime Minister Narendra Modi's government, and industry has increasingly taken on rocket manufacturing since. [1]

ISRO is not a small agency being wound down. It has sent a spacecraft to Mars, landed near the Moon's south pole, built its own launchers and is preparing India's first crewed spaceflight. [1]

It flew EOS-05, an Earth-watching satellite of roughly 2.5 tons, to a high orbit last week, replacing one lost in a launch failure in 2021. [5]

Why it matters. Watch whether the Department of Space publishes an actual list of what is being transferred; until it does, ISRO's staff are reading about their own work in the press.

The US Space Force is beginning work on a new ground control system for its future GPS satellites, SpaceNews reports. It is applying lessons from OCX, a ground control programme the US defence department cancelled earlier this year, after 15 years of development and $6.27 billion. GPS is the constellation of satellites that gives position, navigation and timing to military and civilian users worldwide; the satellites fly, but the ground software that commands them and handles their signals is a separate build. [2]

Why it matters. Ground software has no launch to watch and no photograph, so it is the part of a space programme that can run over for a decade without anyone outside noticing.

The US updated its National Space Transportation Policy in a presidential memorandum on 20 August, calling for launch ranges able to support more than 1,000 launches and reentries a year by 2030. There were 181 launches from US soil in 2025, and about a tenth of that in 2013. Brian Weeden of the Aerospace Corporation says the shortage is not launchpads but the plumbing around them: bridges that are choke points, fuel storage, and buildings to receive payloads. [4]

Why it matters. It moves the argument from rockets to concrete. The thing that limits how often anyone can fly is a shed big enough to unpack a satellite in.

The UK government will put 30 million pounds into SaxaVord Spaceport, on the Shetland Islands off Scotland's north coast, Aviation Week reports. The money funds two additional launchpads as the site moves toward regular commercial launches. Assured access to orbit is named as a priority of the country's new Space Strategy. No British-built rocket has yet reached orbit from British soil. [3]

Why it matters. The UK government is paying to expand a spaceport it does not run, days after a German company reached orbit from a Norwegian one.

Blue Origin, the space company owned by Amazon founder Jeff Bezos, has given no meaningful update on its heavy-lift New Glenn rocket for about a month, Ars Technica reports. The rocket has been grounded since an explosion on the pad at Cape Canaveral in Florida in May. The company says it is aiming to fly again by the end of the year, which Ars says there is good reason to doubt. In the same period it broke ground on a new payload processing facility in Florida. [5]

Why it matters. Payload processing buildings are exactly the shortage Brian Weeden names in the spaceport story above, so the grounded company is building the scarce thing rather than the rocket.

Isar Aerospace, the German company that reached orbit from Norway at the weekend, is now working toward the first paid flight of its Spectrum rocket while scaling up production and adding launch sites, Aviation Week reports. Rockets three through seven are already in manufacturing. Payload reports it is the first company in the European Launcher Challenge, a European Space Agency programme backing new launch firms, to reach orbit. [6][7]

Why it matters. One flight proves a rocket can work. A production line is what decides whether Europe can actually buy launches at home.

The International Space Summit takes place in Paris on 9 and 10 September, bringing together heads of government, ministers, industry and astronauts. Josef Aschbacher, who runs the European Space Agency, will tell them that low Earth orbit is entering a new phase. He will say the Moon is becoming a place for sustained operations, and that the groundwork for Mars missions is being laid now. ESA says its own job is to present technically sound and affordable options, and that the strategic direction belongs to member states. [8]

Why it matters. The agency is saying openly that it decides nothing. Whatever Europe does next is decided by the ministers in that room.

NASA's Mars sample return programme was meant to bring rock samples back to Earth. It is now on indefinite hold. The agency's three upcoming robotic Mars missions were chosen through what The Planetary Society calls an opaque process. That is a departure from the competitive, peer-reviewed selection guided by the decadal survey, the community's own ten-year priority list, which has shaped NASA science for a generation. One of the three, SR-1 Freedom, would fly the first nuclear-fission-powered interplanetary spacecraft. [19]

Why it matters. Scientists are objecting to how the missions were picked rather than to the missions, which is a complaint about who is allowed in the room.

Jessica Meir of NASA and Sophie Adenot of the European Space Agency spent six hours and 49 minutes outside the International Space Station on 1 September, closing a month with four spacewalks in it. They fitted a new reflector to the forward end of the Harmony module to help arriving spacecraft judge their approach, swapped a camera on the station's truss and swabbed the outside for microbes. Work on the Alpha Magnetic Spectrometer's radiator was deferred to a future walk. It was the 284th spacewalk in the station's history. [9][10][21]

Why it matters. None of the four was an emergency. The station only keeps working because people go outside on a schedule and change parts.

A Rocket Lab spacecraft used an optical instrument built by Lawrence Livermore National Laboratory, a US government weapons and physics laboratory in California, to track another satellite during a Space Force exercise, SpaceNews reports. The exercise, Victus Haze, tested how quickly a spacecraft can be launched and then put to work inspecting an object already in orbit. [12]

Why it matters. The lab that designs nuclear weapons now supplies the camera that lets one satellite watch another, which is a plain measure of who the customer for orbital cameras has become.

European Commission President Ursula von der Leyen announced a 200 million euro package for Greenland on Monday, to be spent this year and in 2027 on internet connectivity, mining, energy, education, fisheries and housing. She signed the declaration with Greenland's Prime Minister Jens-Frederik Nielsen and Denmark's Prime Minister Mette Frederiksen. A Reuters photograph shows the three visiting the satellite operator Eutelsat OneWeb in Nuuk. Greenland is a semi-autonomous territory of Denmark, and the EU has stepped up its attention since US President Donald Trump began saying the United States should take control. [13][14]

Why it matters. Cables do not reach most of Greenland, so a satellite company is what digital connectivity there actually means.

Progress 96 is an uncrewed Russian cargo spacecraft. It is due to lift off from Baikonur in Kazakhstan at 12:15 in the afternoon US eastern time on Wednesday 9 September. It carries about three tons of food, fuel and supplies for the International Space Station. NASA will carry the launch and docking live. Progress craft are the Russian side's routine supply run, and they burn up in the atmosphere at the end of the mission. [11]

Why it matters. The station holds seven people and grows none of its own food. Everything they eat, drink and breathe arrives on a flight like this one.

The Coronagraph Instrument aboard NASA's Nancy Grace Roman Space Telescope was powered up in space on 1 September, starting at 7:27 in the morning US eastern time and finishing 55 minutes later. A coronagraph blocks a star's glare with a mask and bending mirrors, so the far fainter light reflected off a planet beside it can be photographed. Months of calibration follow before it does science. It is aimed at planets that are older, colder and closer to their star than the ones this method has managed so far. [17]

Why it matters. Almost every planet found around another star has been inferred from a dip or a wobble. This instrument is built to take an actual picture.

New computer simulations suggest Earth's Moon could have come together within hours of the collision that made it, rather than over a much longer period. The leading account of the Moon's origin is that a Mars-sized body called Theia struck the young Earth at an angle and threw debris into orbit. A team led by Adeene Denton at the South-west Research Institute added the strength of the rock to the model, and found that warmer bodies are weaker, which changes how the collision plays out. Robin Canup's simulations have anchored this field since 2001. [16]

Why it matters. This is a model, not a measurement. Nobody was there, and the only evidence is Moon rock and the physics you choose to put in the code.

Researchers publishing in Scientific Reports built an artificial-intelligence model of collision risk in low Earth orbit, the busy band a few hundred kilometres up where most satellites fly. It uses gradient-boosted decision trees, a standard method that learns patterns from data, to estimate how altitude, orbital tilt, mass and crowding combine into collision risk. Their conclusion is that meaningful increases in the number of satellites are possible for only a moderate rise in predicted risk. [18]

Why it matters. Every operator wants a number saying orbit is not full yet, and this is one. It is a prediction from a model, not a measurement of anything that has happened.

The OECD, the Paris-based group of mostly rich countries' governments, published a report on the spread of satellite Earth-observation data and what it means for privacy, security and trust. Better optics, cheap cloud computing and artificial intelligence have made high-quality satellite imagery both better and far easier to get hold of. The same report says that combination also creates risks, including for national security. [20]

Why it matters. The pictures used to be taken by governments and read by governments. Now a company takes them and software reads them, which changes who knows what about whom.

Before dawn on Tuesday a slim crescent Moon, under a tenth lit, sits about five degrees above Jupiter low in the east-north-east. Later the same day the Moon passes in front of the planet, an event astronomers call an occultation, in full daylight. Jupiter was lost in the Sun's glare from early July to mid-August, so a telescope before dawn also shows what its cloud belts have been doing since. Daytime viewing needs a telescope and a clear sky. [15]

Why it matters. It is the same geometry that lets astronomers measure distant worlds: you learn about a thing by timing exactly when something else covers it.
