How using the cloud can rev up the search for asteroids

Astronomers have used a cloud-based technique pioneered at the University of Washington to identify and track asteroids in bunches of a hundred or more. Their achievement could dramatically accelerate the quest to find potentially threatening space rocks.

The technique makes use of an open-source analysis platform known as Asteroid Discovery Analysis and Mapping, or ADAM; plus a recently developed algorithm called Tracklet-less Heliocentric Orbit Recovery, or THOR. The THOR algorithm was created by Joachim Moeyens, an Asteroid Institute Fellow at UW; and Mario Juric, director of UW’s DiRAC Institute.

Teaming up ADAM and THOR may sound like a cross between a Bible story and a Marvel comic, but this dynamic duo’s superpower is strictly scientific: When ADAM runs the THOR algorithm, the software can determine the orbits of asteroids, even previously unidentified asteroids, by sifting through any large database of astronomical observations.

ADAM has been a long-term project for the Asteroid Institute, a program of the California-based B612 Foundation.

“Discovering and tracking asteroids is crucial to understanding our solar system, enabling development of space, and protecting our planet from asteroid impacts,” former NASA astronaut Ed Lu, the Asteroid Institute’s executive director, said today in a news release. “With THOR running on ADAM, any telescope with an archive can now become an asteroid search telescope.”

NASA funds big ideas from small businesses

How do you keep moondust from gumming up the works in NASA’s future spacesuits and spacecraft? That’s one of the issues addressed in the latest batch of projects backed by NASA’s Small Business Innovation Research program.

“NASA is working on ambitious, groundbreaking missions that require innovative solutions from a variety of sources – especially our small businesses,” NASA Deputy Administrator Pam Melroy said in a news release. “Small businesses have the creative edge and expertise needed to help our agency solve our common and complex challenges, and they are crucial to maintaining NASA’s leadership in space.”

Four SBIR research contracts will go to Washington state companies. And two of those contracts are going to Everett-based Off Planet Research. One Off Planet project focuses on the development of a flexible fiber seal that will hold up in dusty environments.

Starliner space taxi’s success paves way for crewed flight

Boeing’s CST-100 Starliner space capsule landed safely amid the sands of New Mexico after a six-day test flight to the International Space Station and back.

This trip was uncrewed — assuming you don’t count a sensor-equipped mannequin nicknamed Rosie the Rocketeer as a crew member. But living, breathing astronauts could fly on Starliner as soon as this year.

All went well today with Starliner’s descent from the space station and its parachute-aided, airbag-cushioned landing at White Sands Missile Range, Cheers arose at NASA’s Mission Control in Houston, where the final stages of the flight test were being tracked.

NRO strikes multibillion-dollar deals for satellite images

Three satellite imaging companies are in line to receive billions of dollars from the National Reconnaissance Office over the next decade, thanks to a string of contracts announced today.

The companies are the same satellite operators who won study contracts from the NRO three years ago: BlackSkyMaxar Technologies and Planet.

BlackSky, which got its start in Seattle and is now headquartered in Virginia, says its contract for Electro-Optical Commercial Layer imagery sets up a five-year base subscription with a starting value of $85.5 million, plus options to extend the contract to 10 years. If all options are exercised, total contract value would be $1.021 billion.

Colorado-based Maxar, which was the first to provide commercial satellite imagery to the NRO, would be paid $300 million per year for the first five years, plus options for $1.74 billion in the following five years. Total potential value would be $3.24 billion. California-based Planet didn’t disclose the value of its contract.

BlackSky’s stock nearly doubled in value today, ending the trading session at $2.33 per share. Maxar’s share price rose almost 18% to close at $28.86. Meanwhile, Planet’s stock was up 14%, finishing up at $5.73.

Frequently updated commercial imaging has proven its value to the U.S. intelligence community in crises such as the war in Ukraine. The NRO said today’s deals represent the agency’s largest-ever commercial imagery contract effort.

Spaceflight’s latest orbital tug debuts on SpaceX launch

A new type of controllable orbital transfer vehicle built by Seattle-based Spaceflight Inc. made its debut today when SpaceX sent dozens of satellites into orbit on a Falcon 9 rocket.

SpaceX’s Transporter-5 mission, which is part of the company’s rideshare program, lifted off from Cape Canaveral Space Force Station in Florida at 2:35 p.m. ET (11:35 a.m. PT):to send 59 small spacecraft to space. Minutes after stage separation, the Falcon 9’s reusable first-stage booster made a rare land-based touchdown at SpaceX’s Landing Zone 1, not far from the launch site.

The piggyback spacecraft were to be deployed from the rocket’s upper stage into low Earth orbit, or LEO, over the course of a little more than an hour. One of those spacecraft is Spaceflight’s Sherpa-AC1, the latest in the company’s line of Sherpa orbital transfer vehicles, also known as space tugs.

Sherpa tugs are designed to go out from their launch vehicles and deliver an assortment of small satellites to different orbits. The tugs can also carry hosted payloads, which do their thing while remaining attached to the tug.

The Sherpa-AC adds capabilities for attitude control (hence the “AC”) and tracking. An onboard flight computer keeps track of the tug’s location in space, and a command and control system can keep the spacecraft pointed in the right direction. There’s also a two-way communication system, an electrical power system and a basic thermal control system.

Space startups get a cloud-based boost from Amazon

For the 10 startups participating this year in Amazon Web Services’ Space Accelerator program, the sky is not the limit.

One company is building the next generation of ultra-high-resolution satellites for Earth observation. Another startup is developing electric propulsion systems for spacecraft and satellites in low Earth orbit. And yet another venture is working on a new type of space capsule that could someday carry cargo and crew to the moon.

“This year’s finalists brought forward pioneering ideas that will draw valuable insights from the depths of the ocean floor to the surface of the moon, and nearly everything in between,” Clint Crosier, director of AWS for Aerospace and Satellite Solutions, said today in a blog post.

Today’s announcement about the Class of 2022 follows up on last year’s inaugural Space Accelerator program. Hundreds of startups applied to take part in the program’s second year, and AWS worked with the AlchemistX accelerator management program to select these 10 finalists.

Starliner docks with space station after ‘excruciating’ wait

Boeing’s CST-100 Starliner space taxi docked with the International Space Station for the first time today during an uncrewed flight test, marking one more big step toward being cleared to carry astronauts to orbit. But it wasn’t easy.

“The last few hours have been excruciating,” Kathy Lueders, NASA’s associate administrator for space operations, acknowledged during a post-docking teleconference for journalists.

Despite a few glitches, Lueders and other leaders of the NASA and Boeing teams said they were generally pleased with Starliner’s performance, beginning with its May 19 launch from Florida and continuing with today’s hours-long series of orbital maneuvers.

“We’ve learned so much from this mission over the past 24 hours,” Lueders said.

Boeing’s Starliner space taxi lifts off for second test flight

Two and a half years after an initial orbital flight test fell short, Boeing is trying once again to put its CST-100 Starliner space capsule through an uncrewed trip to the International Space Station and back.

United Launch Alliance’s Atlas 5 rocket sent Starliner spaceward from Cape Canaveral Space Force Station in Florida at 6:54 p.m. ET (3:54 p.m. PT) today. Boeing and NASA are hoping that this second orbital flight test, known as OFT-2, will pave the way for Starliner’s first crewed flight later this year.

Within OFT-2’s first hour, Starliner separated from the Atlas 5 rocket’s Centaur upper stage and executed an engine burn to reach its intended orbit. “It’s a major milestone to get behind us, but it is really just the beginning,” NASA commentator Brandi Dean said. “We’ve got a number of demonstrations now that the Starliner will have to go through ahead of its International Space Station arrival.”

Boeing has received billions of dollars from NASA to develop Starliner as an alternative to SpaceX’s Crew Dragon for sending astronauts into orbit. NASA’s arrangement with SpaceX and Boeing has been compared to a taxi service, with the space agency paying the spacecraft providers for rides.

Nuclear power in space? Pentagon boosts two projects

Two Seattle companies have won Pentagon contracts to develop nuclear-powered prototypes for space applications, with orbital demonstrations set for 2027.

The Defense Innovation Unit says Ultra Safe Nuclear Technologies has been tasked with demonstrating a chargeable, encapsulated nuclear radioisotope battery called EmberCore for propulsion and power applications in space.

Plutonium-powered radioisotope batteries have been in use for decades, going back to the Apollo era. For example, NASA’s Perseverance and Curiosity rovers are relying on such batteries to provide the heat and electricity for their operations on Mars.

EmberCore would provide 10 times as much power as those batteries, producing more than 1 million kilowatt-hours of energy using just a few pounds of fuel.

Another Seattle-based venture, Avalanche Energy, will receive backing from the Defense Innovation Unit to continue development of a compact fusion device known as Orbitron. The device, which is about the size of a lunchbox, would use electrostatic fields to trap ions in conjunction with a magnetron electron confinement system.

The resulting fusion reaction would produce energetic particles for generating either heat or electricity, which can power a high-efficiency propulsion system.

Mammoth zero-emission mining truck makes its debut

After years of development, the world’s largest zero-emission vehicle was unveiled today at a South African platinum mine, with a hydrogen-fueled hybrid powerplant designed and built by Seattle-based First Mode.

Anglo American’s three-story-tall, 200-ton nuGen hybrid mining truck received a grand sendoff from South African President Cyril Ramaphosa at the Mogalakwena open-pit platinum mine. “It is a smart step for Anglo American, but a giant leap for South Africa’s hydrogen economy as we move into the future,” Ramaphosa said. “The hydrogen economy is beckoning us as a country and as an industry.”

Chris Voorhees, president and CEO of First Mode, said zero-emission industrial power will play a key role in addressing the global climate crisis. Large trucks currently account for 70% to 80% of diesel fuel consumption at Anglo American’s mines, but one nuGen truck is expected to keep the equivalent of carbon dioxide emissions from 700 cars out of the atmosphere.

“At First Mode, we know we are at a ‘fire-everything’ moment,” Voorhees said in a news release. “The urgency in front of us requires that we deploy every tool and every technology to battle climate change. I’m so proud of the team and our partnership with Anglo American, focused on decarbonization at the source to effect the meaningful, necessary change we all seek.”
