From:
Elon Musk
Date:

Excerpt. Only this much of the email has been made public.

final stretch [...] Should happen in the next four to six weeks. [...] approval to fly the rocket with only thrust cutoff, rather than explosive termination. [...] [This] improves hazardous procedures in transportation, on the launch pad and particularly on recovery of the first stage. [...] due to the all liquid fuel configuration and six-fold valve redundancy. [...] significant cavitation margin [...] on track for a maiden launch around the middle of this year.

About this email

Quoted fragments: SpaceX is in the 'final stretch'; regulators approved flying with thrust cutoff instead of explosive termination; the first-stage hold-down test should happen in four to six weeks; and the company is on track for a maiden launch around mid-2004.

Notes

Excerpt only: these are the passages that HobbySpace's RLV News quoted verbatim from the newsletter when it came out; HobbySpace's own paraphrased highlights are not included. The complete newsletter was posted on spacex.com (Updates section), which is no longer online, and no full-text reprint was found. The quotes are short fragments embedded in HobbySpace's 5 March 2004 summary, in the order printed; '[This]' is HobbySpace's insertion. The summary also reports Kestrel reaching 96.4% efficiency and 327s Isp, first-stage pressurization tests in Texas, and a Falcon User's Conference on 25-26 March 2004.
