The spacecraft will provide fast transport between Earth and the moon—and beyond.

Picture this: World War III is just hours away. In the cold vastness of space, enemy robotic spacecraft are slowly adjusting their orbits and preparing to launch a surprise attack on the U.S.’s fleet of satellites. The uncrewed craft, with robotic arms strong enough to disable a satellite, are creeping up on American spacecraft, about to deal a knockout blow to the U.S. military.

But down on Earth, U.S. Space Force guardians have been keeping track of the assassin craft, knowing that in order to present as low a profile target as possible, they have just enough fuel for one attack. At the last minute, after the enemy satellites have committed to attack, the command activates the nuclear thermal propulsion (NTP) engines on the American satellites, quickly boosting them into a higher orbit and safely out of range.

In June, San Francisco-based startup Orbit Fab launched a prototype refueling station into Earth’s orbit — but rather than allowing astronauts to venture into deep space, this system is meant to give old satellites a new lease on life.

That’s a compelling idea, and now the company has locked down $10 million in funding to further it. Our planet’s orbit is getting cluttered with old and new satellites, increasing the risks of a collision and adding to an existing space junk problem.

Orbit Fab’s Tenzing Tanker-001, an early prototype satellite fuel tanker, launched into orbit as part of SpaceX’s Transporter-2 rideshare mission on June 30.

One of SpaceX’s oldest rockets launched on a historic 10th flight, carrying the first stack of Starlink satellites into space in more than two months before sticking a landing at sea to cap the successful mission.

The previously-flown Falcon 9 rocket blasted off from Space Launch Complex 4E at Vandenberg Space Force Station at 11:55 p.m. EDT (8:55 p.m. PDT, or 355 Sept. 14 GMT), marking the company’s 22nd launch of the year. It also marked a record 10th flight for this particular first stage booster.

WASHINGTON — NASA has selected SpaceX to launch the last in a series of geostationary weather satellites that had previously been launched by United Launch Alliance.

NASA announced Sept. 10 that it awarded a contract to SpaceX for the Falcon Heavy launch of the Geostationary Operational Environmental Satellite (GOES) U spacecraft. The launch is scheduled for April 2024 from the Kennedy Space Center in Florida. The agency said the contract is valued at $152.5 million.

GOES-U is the fourth and final satellite in the GOES-R series of satellites, which monitor terrestrial and space weather from geostationary orbit. GOES-R launched in November 2016 and was renamed GOES-16, operating from the GOES East slot at 75 degrees west in GEO. GOES-S launched in March 2018 and became GOES-17, operating from the GOES West slot at 137 degrees west. GOES-T is scheduled to launch in January 2022 and will replace GOES-17 because of problems with that satellite’s main instrument, the Advanced Baseline Imager.

When a cloudy plume of ice and water vapor billows up above the top of a severe thunderstorm, there’s a good chance a violent tornado, high winds or hailstones bigger than golf balls will soon pelt the Earth below.

A new Stanford University-led study, published Sept. 10 in Science, reveals the physical mechanism for these plumes, which form above most of the world’s most damaging tornadoes.

Previous research has shown they’re easy to spot in satellite imagery, often 30 minutes or more before severe weather reaches the ground. “The question is, why is this plume associated with the worst conditions, and how does it exist in the first place? That’s the gap that we are starting to fill,” said atmospheric scientist Morgan O’Neill, lead author of the new study.

NATIONAL HARBOR, Md. — Yahsat has selected SpaceX to launch its next-generation Thuraya mobile connectivity satellite in 2,023 the companies announced Sept. 8.

A Falcon 9 will launch the Thuraya 4-NGS satellite, being built by Airbus Defence and Space for UAE-based Yahsat, in the second half of 2023. The companies did not disclose terms of the launch contract.

Rocket Lab signed a five-launch contract with European satellite data company Kinéis. The deal adds to the space company’s backlog.

Private orbital debris removal company Astroscale has validated its magnetic capture system that is designed to tackle the problem of space debris. Its End-of-Life Services by Astroscale-demonstration (ELSA-d) servicer satellite managed to capture a simulated piece of space debris in orbit for the first time using the system.

Space debris is a serious and growing problem as popular orbits around the Earth become increasingly cluttered with defunct satellites, boosters, and other flotsam that present the hazard of an increased probability of a bit of debris striking a working spacecraft at hypersonic speeds.

The boom in LEO satellites will probably change the lives of customers who’ve struggled for high-speed internet—but only if they can afford it.
