SAN FRANCISCO – PredaSAR, a Florida startup led by retired Air Force Maj. Gen. Roger Teague, raised $25 million in seed funding for its plan to build a constellation of at least 44 Synthetic Aperture Radar (SAR) satellites.

“The Defense Department has been after a space-based radar solution for many years,” Teague told SpaceNews. “There’s a need for a SAR moving-target indicator… I believe there is going to be strong market demand.”

PredaSAR was founded in 2019 by Marc Bell, an entrepreneur and investor who is the chairman and co-founder of Terran Orbital, which owns Tyvak Nano-Satellite Systems. Bell now serves as PredaSAR’s chairman. Before closing the seed funding round, PredaSAR hired Tyvak to build its first two satellites, Bell said.

The Deep Space Climate Observatory – a satellite that warns of incoming space storms that could knacker telecommunications on Earth – is up and running again after being shut down for eight months by a technical glitch.

Launched in 2015 aboard SpaceX’s Falcon 9 rocket, the bird, known as DSCOVR for short, was sent into orbit between the Earth and the Sun. Circling at a distance of about a million miles away from terra firma, satellite sports instruments designed to detect approaching geomagnetic storms, and alerts us before highly energetic particles from the solar wind pelt our planet.

Boeing is offering signing bonuses up to $30,000 for experienced satellite engineers and procurement specialists, saying Friday needs the staff “to help build assets for the U.S. Air Force and its allies.”

The company posted a notice about its hiring on LinkedIn, listing more than open 75 jobs for what Boeing said were its “rapidly growing” satellite program efforts.

“We have an urgent need for Security Cleared Satellite Engineers to help build assets for the U.S. Air Force and its Allies. We’re offering a potential $30k sign-on bonus,” the posting said.

Two unmanned commercial satellites have docked in orbit for the first time. On February 25, Northrop Grumman’s Mission Extension Vehicle-1 (MEV-1) linked up with the Intelsat 901 (IS-901) communication satellite at an altitude of 22,416 mi (36,076 km) above the Earth as part of a project to extend the service life of satellites that are running low on propellants.

The building and launching of satellites is extremely expensive, so it’s more than just frustrating when a perfectly good spacecraft has to be disposed of or abandoned simply because it has run out of the propellants needed to keep it in its proper orbit and pointed at Earth. There have been a number of solutions proposed for this problem – in this case Northrop’s MEV-1 is designed to match orbits with aging satellites, dock, and take over the job of maintaining orbit and attitude.

MEV-1 was launched on October 9, 2019, and then executed a series of orbital maneuvers to rendezvous with IS-901, 180 mi (290 km) above geosynchronous orbit. Northrop says the target communication satellite was removed from service last December after over 19 years of service and its customers transferred to other Intelsats.

At 35 meters, the wingspan of the new BAE Systems aircraft equals that of a Boeing 737, yet the plane weighs in at just 150 kilograms, including a 15 kg payload. The unmanned plane, dubbed the PHASA-35 (Persistent High-Altitude Solar Aircraft), made its maiden voyage on 10 February at the Royal Australian Air Force Woomera Test Range in South Australia.

“It flew for just under an hour—enough time to successfully test its aerodynamics, autopilot system, and maneuverability,” says Phil Varty, business development leader of emerging products at BAE Systems. “We’d previously tested other sub-systems such as the flight control system in smaller models of the plane in the U.K. and Australia, so we’d taken much of the risk out of the craft before the test flight.”

The prototype aircraft uses gallium arsenide–based triple-junction solar cell panels manufactured by MicroLink Devices in Niles, Ill. MicroLink claims an energy conversion efficiency of 31 percent for these specialist panels.

WASHINGTON — Lockheed Martin will acquire the satellite technology assets of Vector by default after a bankruptcy court received no qualified bids by a deadline last week.

In a Feb. 24 filing in the United States Bankruptcy Court for the District of Delaware, lawyers overseeing the bankruptcy proceedings for Vector said that they received no qualifying bids for the company’s GalacticSky software-defined spacecraft technology by a Feb. 21 deadline.

As a result, Lockheed Martin, which provided debtor-in-possession financing when Vector filed for Chapter 11 bankruptcy in December, will obtain the assets with a “stalking horse” bid of $4.25 million, according to the terms of a Jan. 24 filing. That deal will be finalized at a Feb. 28 court hearing.

There are currently about 22,000 tracked objects in LEO, some of which are smaller than one centimeter. The focus of many current plans has been on the active removal of current debris.

But with a projected 57,000 new satellites expected to launch by 2029, the question becomes: how to prevent new debris? Currently, at Purdue University’s School of Aeronautics and Astronautics, David Spencer and his team are working on a passive debris removal system using drag sail deorbiting technology where these passive deorbiting systems are embedded within a spacecraft for deorbiting at the end of the spacecraft’s lifetime.

Licensed by Vestigo Aerospace and funded through a Purdue University Research Foundation grant, Spencer and his team hope to launch a drag sail prototype with Texas-based Firefly Aerospace, no earlier than this April. Right now, Spencer is the project and mission of LightSail 2, a solar sail currently in orbit.

The second Ariane 5 mission of the year lifted off from the Guiana Space Centre in Kourou, French Guiana, in South America on a rideshare mission that launched the GEO-KOMPSAT-2B and JCSAT-17 satellites for South Korea and Japan, respectively.

The launch occurred at the opening of a 62 minute launch window at 22:18 UTC.
