RS-27 – amerykański silnik rakietowy zasilany paliwem ciekłym, produkowany przez Rocketdyne i wykorzystywany do zasilania pierwszych stopni rakiet Delta 2000, Delta 3000, Delta 5000, a także pierwszej serii rakiet Delta II (6000).
Silnik ten jest technologicznym rozwinięciem silnika H-1, używanego do napędzania rakiet Saturn I oraz Saturn IB. Powstał w celu zastąpienia silników MB-3, wykorzystywanych we wcześniejszych wersjach rakiet Delta[1][2]. W późniejszych latach na bazie RS-27 zostały zbudowane silniki RS-27A, przeznaczony dla rakiet Delta II (7000) oraz Delta III[3][4], a także RS-56, wykorzystywany w rakietach Atlas II[5].

Flag of the United States.svg
The flag of Navassa Island is simply the United States flag. It does not have a "local" flag or "unofficial" flag; it is an uninhabited island. The version with a profile view was based on Flags of the World and as a fictional design has no status warranting a place on any Wiki. It was made up by a random person with no connection to the island, it has never flown on the island, and it has never received any sort of recognition or validation by any authority. The person quoted on that page has no authority to bestow a flag, "unofficial" or otherwise, on the island.

On Launch Pad 17-B at Cape Canaveral Air Force Station in Florida, workers check the lines attached to the lower end of the United Launch Alliance Delta II rocket before it is lifted into the mobile service tower. The rocket is the launch vehicle for the THEMIS spacecraft, consisting of five identical probes, the largest number of scientific satellites ever launched into orbit aboard a single rocket. This unique constellation of satellites will resolve the tantalizing mystery of what causes the spectacular sudden brightening of the aurora borealis and aurora australis - the fiery skies over the Earth's northern and southern polar regions. After the first stage is in the mobile service tower on the pad, nine solid rocket boosters will be placed around the base of the first stage and attached in sets of three. THEMIS is scheduled to launch aboard the Delta II at 6:07 p.m. EST on Feb. 15.
