Welcome to Edition 2.01 of the Rocket Report! This week marks one year since the first report. What started as an experiment has grown into something that a lot of people read.

Virgin performs full-duration hotfire test. On Tuesday, Virgin Orbit announced that it had performed the "final full-duration, full-scale, full-thrust—hell, full everything—test firing" of its LauncherOne rocket's first stage. The firing lasted for more than 180 seconds and was entirely successful, the company reported. Virgin said the rocket, which will be launched from beneath the wing of an airplane, was within an "arm's reach" of its first orbital flight test.

Time to fly ... With the full-duration hotfire test completed, Virgin officials said they have now tested every single aspect of the LauncherOne rocket, from hardware through software, on ground-based stands. All that remains between now and the orbital test flight is final assembly of the first rocket and a few additional test flights of Virgin's modified 747, Cosmic Girl. We'll hope for a launch some time this summer.
