On the same day as the launch of Artemis I to
the Moon, Astrobotic issued this
showing the Peregrine spacecraft being
readied for shipment.
from Reuters shows that this is the debut of the
Vulcan rocket.
This line is priced at about $110 million per
launch. When
successful it will offer an American made
alternative to the Russian
engines commonly used in the industry. The
delay from end of 2022
was at the request of Astrobotic.
shows the Mass Properties and Vibe Test. The
former weighs the
vehicle and determines the location of the Center of
Mass and various
inertial properties. These are needed for the
attitude control
system. The second test is to shake the
hardware to test its
strength for withstanding launch.
The rocket stack
used for our launch will be a Vulcan booster
powered by two BE-4 engines from
Blue
Origin, and the upper stage will be a
Centaur V.
These are new motors that run on Methane (LNG),
and have more thrust
that the Space Shuttle Main Engines. Once
operational, they will
replace the ones that are normally bought from the
Russians, and that
will be very good in these uncertain political
times.
March 2023 -
First Stage (Booster) Tanking Test
The tanking system of this brand new rocket design
was tested at launch pad LC41 and described in
this
update. A nice video summarizing the
tests and a glance at the payloads is
here.
April 2023 -
Upper Stage Tank Test
This
video
shows a explosion during a test of the Centaur V
upper stage tank.
This may be cause for delay. The launch
window will be in monthly
intervals due to the Lunar flight
trajectory. Indeed in early
May, we received an email update that launch would
be delayed from the
May 2023 date.
June 2023 - BE-4
Test Fire
On June 7 2023, the twin BE-4 engines running on
Methane were test
fired successfully on the launch pad. This
is clearly an
important milestone to launch. In the next
step, I would expect
to next hear that Astrobotic can ship Peregrine to
the Cape for launch.
October 26 2023 -
Installing the Booster Stage
ULA posted this sequence on their
Twitter
page to show the Booster with the twin BE-4
engines being raised onto the pad.

Booster being raised onto the pad.
October 27 2023 - Shipping to the Cape
After a long delay due to the upper stage
issue on the Centaur,
the Peregrine spacecraft was loaded onto a truck
and shipped to the
Kennedy Space Center.
November 2023
We saw the booster being raised onto the
pad in the image above,
and ULA released an image of the Centaur V upper
stage this
month. It gets stacked on top of the
booster, and then Peregrine will be stacked on top
of that. At
the pad, the booster will be ignited first, and
carry the whole stack
aloft. It will then be dropped, and the
upper stage takes over
pushing Peregrine to the Moon.

In this same month, Astrobotic sent out
invites for the launch party. It also
included a link to the
info packet.
Note
that the Aruba sand will be sent via the Moonbox
program.
The landing spot has been changed from Lacus
Mortis to "
Gruithuisen
Domes". This area was named after the
German astronomer
Franz
von Gruithuisen.

Also this
month, NASA announced that two Goddard-led
development teams would fly on
Peregrine. These are
the Laser
Retroreflector Array (LRA) and Peregrine
Ion-Trap Mass Spectrometer (PITMS).

December 2023
Early in this month, they performed a Wet
Dress Rehearsal
(WDR). This is where the rocket is tanked to
check for
leaks. As you can see here with the tweet
from Tory Bruno (ULA
President) it all went well and launch date is now
set for Jan 8, 2024.

Later this same month, Astrobotics sent out
an
update
showing the spacecraft mounted onto the payload
adapter. The
update also disclosed that the anticipated landing
date on the Moon
will be February 23, 2024. This payload
adapter is custom made
for this spacecraft so that it can be bolted onto
the Centaur V upper
stage.
This
video
released December 22, 2023 shows the entire
rocket complete and ready for launch.

Here you see Peregrine encapsulated in its
fairing being
stacked onto upper stage.
Launch!
