Space, in brief

Pixxel, an Indian company that builds Earth-watching satellites, said on Monday it had raised $100 million. [1]

The round was led by Temasek, which invests the Singapore government's money, and Seraphim, a British firm that backs space companies. [1]

Two backers it already had, Radical Ventures and growX Ventures, put in more, and two new ones joined: 360 ONE Asset and IMM Investment. [1]

That takes the total Pixxel has raised since it started to $195 million. [1]

Reuters calls it the largest single funding round by a space technology company in India. [1]

Google is one of Pixxel's existing backers. [1]

The money goes into building more satellites, including in the United States, where Pixxel wants to sell to government buyers. [2]

Pixxel's satellites are hyperspectral: they read the ground by splitting its light into many narrow bands, which shows what a surface is made of in a way an ordinary camera cannot. [1]

The new money also goes to Pixxel's Honeybee group of satellites and to sharper optical imaging satellites. [1]

Pixxel also sells software called Aurora, which turns the pictures into answers for governments and companies. [1]

The company was founded by Awais Ahmed and is one of the firms that appeared after India opened its space industry to private companies. [1]

Neither report gives what Pixxel is now worth, names a site in the United States, or names an American customer. [1][2]

Why it matters. Watch for the first named American site or the first named American customer. Neither report carries one, so the United States half of this is a budget without an address. [1][2]

Europe's Ariane 6 rocket flew its first mission to geostationary transfer orbit on 27 August, lifting off from Kourou in French Guiana and releasing the MTG-I2 weather satellite about thirty minutes later. A transfer orbit is a long oval; the satellite has to round it out itself, with its own engine, to reach a fixed post nearly 36,000 kilometres above the equator. Renamed Meteosat-14, it will then watch Europe, Africa and the Middle East without a break. [7]

Why it matters. Eumetsat, the European weather agency that owns the satellite, put its previous Meteosat on an American Falcon 9 in 2025 because Ariane 6 was late, so this flight is a customer coming back. Ariane 6 has now flown eight clean missions in nine attempts since 2024. [7]

A Falcon 9 lifted off from Vandenberg Space Force Base in California on Sunday at 1426 GMT carrying 27 more Starlink internet satellites, which it released 62 minutes later. The first stage came back eight and a half minutes after launch and landed on a ship in the Pacific called Of Course I Still Love You. It was that booster's nineteenth flight. SpaceX's record for a single booster is thirty-seven, set on 25 August. [3]

Why it matters. It was the 103rd Falcon 9 mission of 2026, and 80 of those flights carried SpaceX's own Starlink satellites, a network of more than 11,000 working spacecraft by the count of the satellite tracker Jonathan McDowell. Starlink now flies only from California, because SpaceX has handed its Florida pads to Starship. [3]

Little red dots are a class of object the James Webb Space Telescope began finding in its deep surveys, and astronomers have not agreed what they are. In the journal Nature Astronomy, a group of them argues the dots are black holes of roughly one to ten million times the Sun's mass, wrapped in gas so thick that the gas itself glows at about 5,000 degrees. An explanation using only stars, they say, would need masses too large to fit the infrared light. [6]

Why it matters. If they are right, the dots are the earliest stage of a black hole and its galaxy growing together, which is the part of that story nobody has watched. The paper lists the observations that would settle it, and none of them has been made yet. [6]

A source called eRASSU J0608 gives off a bright X-ray pulse every 374 seconds, and astronomers used the NICER and Einstein Probe X-ray observatories to work out why. It is two white dwarfs, the Earth-sized cinders left when Sun-like stars run out of fuel, orbiting so close that material pulled off one lands straight on the other. That is what makes the X-rays arrive in bursts rather than as a steady glow. Set against observations from more than three years earlier, the orbit is shrinking fast. [4]

Why it matters. The rate it is shrinking matches what would be expected if the pair were losing energy as gravitational waves, which would make it one of the strongest such sources known among ordinary stars. Nobody can say how strong the signal would be at Earth, because X-rays alone do not give the system's distance. [4]

The heliospheric current sheet is a rippling sheet of charged particles that marks where the Sun's magnetic north meets its south, and it is the largest single structure in the solar system. Until now it had only ever been measured near Earth. Keiichi Ogasawara of the Southwest Research Institute and colleagues used Solar Orbiter, a joint European and American spacecraft, which crossed the sheet on 13 April 2023 about a third of the way in from Earth. [5]

Why it matters. Close in, the sheet turned out to be layered rather than flat, and the amount of iron in the plasma dropped sharply as the spacecraft went through it. The team thinks iron sinks under gravity while it is held in closed magnetic loops near the Sun, before the loops let the gas go. [5]
