Talk:Little Joe II

Doesn't Little Joe II refer to Rhesus Monkeys that included in spaceflight?
Weren't these spaceflights (Little Joe II) used to test monkeys for "manned" spaceflight in anticipation of human "manned" spaceflight? Did somebody miss something here? Stevenmitchell (talk) 17:45, 12 November 2008 (UTC)


 * No, that came before the Little Joe II tests of the Apollo. Bubba73 (talk), 14:40, 14 April 2009 (UTC)


 * Little Joe 2 was the second flight of the smaller Little Joe (rocket) developed for Project Mercury, about four years earlier. JustinTime55 (talk) 17:03, 21 January 2015 (UTC)

Payloads need clarification and citation
There are some problems with the payload weights quoted in this article:
 * Contradiction: the infobox says 30,000 lb., while the Launch vehicle development section says 80,000 lb. was specified (really? Why so much?)
 * The definition of "payload" is really unclear, and always needs to specify the destination (orbit, to Moon, etc.) This rocket was only designed for suborbital (simple ballistic arc) flights to a certain altitude. (Also, what altitude? This needs to be specified.) What exactly does the 30,000 lb. number in the infobox mean? A rocket can carry any payload a certain altitude and distance (aka range, which also should be specified), limited only by the difference between the thrust and the weight of the rocket plus propellant.
 * Payloads are given in the flight table. Do these only include the command module? What about the Launch Escape System, which is really a big part of the test payload. (Even though this isn't included in conventional launch payloads because it wasn't carried into orbit, being jettisoned midway through normal flights.) The numbers quoted look surprisingly small. I would expect, for the test to be meaningful, at least the last flights would have included a flight-weight CM (11-12,000 lb) plus the LES (9,200 lb.); total around 20,000 lb. And what exactly is meant by "airframe weight"?

Also: English units need to be included. JustinTime55 (talk) 18:00, 12 February 2013 (UTC)

Takeoff thrust seems incorrect in the table
49 kN (~11,000 lbs) for the first two test flights isn't enough to offset the weight of the vehicle. Dcs002 (talk) 11:42, 10 May 2014 (UTC)
