Space Investments are No Guarantee

The recent initial public offering for Virgin Orbit, a commercial space launch company that spun-off from Richard Branson’s Virgin Galactic, did not go as well as planned. IG International reported that Virgin Orbit had hoped to raise $483 million as part of the public offering, but only raised $228 million. Moreover, the stock is down about 20 percent.

Virgin Orbit has already had some successfully launches from its modified Boeing 747, but the space launch industry is getting crowded and risky.

In June 2021, Virgin Orbit’s Tubular Bells: Part One mission for the US Department of Defense placed seven satellites to Low Earth Orbit – four R&D CubeSats for the US Department of Defense, two optical satellites for SatRevolution, and the Royal Netherlands Air Force’s first military satellite.  You can learn more about the past and planned US Department of Defense and NASA launches here.

Meteor Watch: Time to Look Up

Looking up may have been useless the other day in Pennsylvania because of the cloud cover, but shaking houses were evidence enough of a meteor exploding in the atmosphere. On New Year’s Day, the incoming meteor exploded over southwestern Pennsylvania with the force of 30 tons of TNT.

The Facebook page for the National Weather Service in Pittsburgh, PA explained the initial situation (image below):

We have been getting a lot of questions about a loud explosion that was heard over southwest Pennsylvania earlier today. Data from GOES-16 may provide a clue.

This image is a product of the satellite’s Geostationary Lightning Mapper function, showing Total Optical Energy (basically, a measure of flash intensity). You can see the flash showing up here in the area of western Washington County, PA at 16:22Z (11:22 EST). This flash does not appear to be connected to any lightning activity in the area. One possible explanation is that a meteor exploded at some level above the ground. We do not have any confirmation of this at this time, but it seems to be the most likely explanation.

Later on, NASA Meteor Watch confirmed it was a meteor breaking up in the atmosphere. The meteor was estimated to be about a yard in diameter and weigh approximately half a ton.
