The ever-growing number of satellites and orbital debris in space prompted calls for change at a House hearing, although how this will be legislated is still under consideration.
At issue is the rise of privately owned satellite constellations by companies such as SpaceX and OneWeb. Satellites today are smaller and more affordable than the big machines of past decades, thanks to advancements in technology. But with fleets of small satellites comes other risks, such as more chances for them to slam into each other. And high-profile near misses are starting to become more common.
“This is one of the most important and rapidly evolving issues facing our ability to operate in space,” said Kendra Horn, D-Okla., chair of the House Subcommittee on Space and Aeronautics, in her opening statement at the hearing in Washington, on Feb. 11.
Two large, defunct and uncontrollable satellites nearly collided in orbit two weeks ago, passing about 60 feet (18 meters) from each other — narrowly avoiding a collision that could have sent thousands of pieces of “space junk” into low Earth orbit. And in late 2019, the European Space Agencyhad to redirect one of its satellites to reduce the risk of a collision; the other satellite operator, SpaceX, did not respond to requests to move its own machine out of the way.
This doesn’t even mention the numerous confirmed examples of space collisions and space junk over the decades that in some cases, are still causing problems today. For example, the International Space Station has changed its orbit in the past to dodge dangerous space debris. Space assets such as weather satellites, telecommunications links and the GPS navigation system for the United States are among the vital links of space infrastructure that could be knocked out if collisions continue.
The U.S. Department of Defense has a catalog of more than 20,000 known space objects, Horn said, although this number has a couple of limitations. The catalog only represents unclassified satellites or objects, and it also indicates the number of trackable objects. There are some things in space that are just too small to be tracked with current technology.
“Space is going to get more crowded,” Horn said, as thousands of new objects join what’s already in space. The SpaceX Starlink constellation could have more than 12,000 satellites alone in a few years, and (besides the collision concern) it already is raising concerns from astronomers for its bright objects blocking night-sky observations.

The House subcommittee commissioned a few experts to speak on how lawmakers can address this problem, under a provision in the 2020 NASA budget to carry out research and development activities concerning space debris mitigation, and to consider a strategy for space situational awareness research and technology.
The solutions proposed were diverse, but for the most part, the experts said it will likely involve using several government entities that could include NASA, the Department of Commerce and other possibilities. There may be some private industry involvement as well.
Public-private partnerships
One possibility is finding more sources for satellite data outside of the Department of Defense. “We need better data,” said subcommittee ranking member Brian Babin (R-Texas), adding that the Department of Defense cannot release all data for national security concerns — and it does not see everything.
Babin suggested that the Department of Commerce could form a partnership with the private sector. It already has experience with regulating standards such as export controls, he said. It also already gives a “light touch” to emerging industries, he pointed out — such as its careful relationship in the 1990s with the Internet Corporation for Assigned Names and Numbers (ICANN) that assigns internet addresses, among many other functions.
Brian Weeden, the Secure World Foundation’s director of program planning, testified as a witness for the subcommittee. He said alerts are already coming from private industry nonetheless. It was LeoLabs, a private American company, that first sent out the alert about the possible 2020 collision in a tweet three days before the event, he said — based on ground-based tracking radars. But he warned the current infrastructure is “dangerously insufficient to face the growing number of space challenges.”
But Commerce is not the only federal entity that could step up to help solve the space junk crisis.
International collaboration
Much of space law rests on precedent, taking into account how things are done in international waters or on the continent of Antarctica (where multiple countries have jurisdiction). For that reason, scholar Ruth Stilwell called for considering the “high seas” as one area where space policymakers could turn for legislation. (Stilwell is an adjunct professor at Norwich University and a senior non-resident scholar at the Space Policy Institute of George Washington University.)
Stilwell called for an “international agreement on standards and behaviors,” with a transition to new space traffic management taking into account the needs of various space players. Whatever the framework is, however, it would need government oversight of some sort. “You can only be a good actor with rules to follow,” Stilwell added later in the hearing. “You can’t expect somebody to be a good actor if rules do not exist.”
There is also concern that by handing space traffic control to big entities like Commerce and a few private companies, other voices (such as smaller companies) could be lost in the space world. “We need to ensure the expertise developed in small communities is not lost in the transition phase,” Danielle Wood, the director of the space-enabled research group at the Massachusetts Institute of Technology, said at the hearing.
While NASA does have expertise in the space domain, the agency doesn’t have all the expertise that other ones have — which is why Joanne Gabrynowicz, professor emeritus of space law at the University of Mississippi Law Center, called for an interagency solution. “There is no one agency who has it all,” Gabrynowicz said at the hearing, referring to other government agency possibilities for managing space traffic.
NASA also has numerous other things to think about, Weeden said in a separate piece of testimony — including its mandate to land astronauts on the moon by 2024 and then move on to Mars. “NASA could do it, but my sense is they will be overwhelmed by all the other things,” Weeden said.
If people don’t act quickly, there is the risk that space debris could lock out the possibility of future missions for a while, if a collision creates pieces of debris that slam into other satellites and break them up, too. (This is known as the Kessler Syndrome.)
Over time the collisions would stabilize, noted Daniel Oltrogge, who is founder and administrator of the Space Safety Coalition, but the effects would still be felt. “By the time it does [stabilize], you have a huge number of small particles out there, and some fragments … that are quite large,” said Oltrogge, who is also chair of the space traffic management space governance task force for the American Institute of Aeronautics and Astronautics.
More subcommittee hearings will be coming up to discuss what to do next.
NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.
Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.
She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.
Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.
“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.
It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.
Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.
Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.
Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.
“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.
He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.
Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.
TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.
Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.
Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.
The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.
The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.
It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.
Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.
Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.
Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.
Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.
Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.
The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.
Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”
Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.
“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.
B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.
Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.
Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.
Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.
“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”
Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”
“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.
Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.
“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
