WHO HAS THE RIGHT OF WAY IN SPACE?

In January of 2020, two decommissioned satellites orbiting Earth made a really close pass. Traveling towards each other with a combined speed of 33,000 mph (53,000 k/hr) the two barely missed each other, coming as close as 210 feet (65 meters).

To make sure an event like this doesn’t happen with any of NASA’s satellites and the internet-providing Starlink satellites from SpaceX, the two groups have agreed to share information about where their spacecraft are flying; settling the question of who has the right of way. Unsurprisingly, it’s NASA, according to the safety agreement, announced March 18, 2021.

And to avoid any confusion, in the event of a potential conjunction, NASA will not move its satellites. This way the agencies don’t run the risk of maneuvering into each other while trying to avoid a collision.

NO, YOU FIRST
With the commercial space sector booming, the issue of avoiding satellite smash-ups in space is also growing.

The number of satellite payloads launched in 2020 jumped to 1,261 — more than twice as many as in 2019 (522), according to statistics maintained by astrophysicist Jonathan McDowell at the Harvard-Smithsonian Center for Astrophysics. The 833 Starlink satellites that SpaceX launched last year account for most of that increase

To help address the issue, in December 2020, NASA released a handbook for aerospace companies, outlining what the agency

NEW COMET NISHIMURA MAY BECOME NAKED-EYE BRIGHT

Newly discovered Comet Nishimura is quickly brightening in the morning sky and may be faintly visible with the naked eye next month. On August 24th observers in North America will be treated to an occultation of Antares.

It’s no small thing for an amateur to wrest a comet from the all-seeing eyes of robotic surveys. But Japanese observer Hideo Nishimura beat those odds on August 12.8 UT. That morning he took three 30-second exposures with a Canon 6D digital camera and 200-mm lens and captured images of a new 11th-magnitude comet in the constellation Gemini. It was his third comet discovery after Comet Nakamura-Nishimura-Machholz (C/1994 N1) and an earlier Comet Nishimura (C/2021 O1). I have nothing against automated hunting, but seeing an amateur’s name on a comet is not only a breath of fresh air but a great achievement.

Comets are like presents under the Christmas tree waiting to be opened. On August 15th the sky cleared and I found a location with an unobstructed view to the east to get my first look. At 4 a.m. local time Comet Nishimura stood just 8° high in the northeastern sky in Gemini. Through my 15-inch (38-cm) Dob I saw it right away at 64× at magnitude 9.8 with a 2.3′ moderately condensed coma. A Swan band filter enhanced its visibility and intensified the apparent brightness of the inner coma, a sign that Nishimura’s comet was rich in volatile carbon gas.
