In most US cities, a city block is between 1 ⁄ 16 and 1 ⁄ 8 mi (100 and 200 m). In Manhattan, the measurement "block" usually refers to a north–south block, which is 1 ⁄ 20 mi (80 m). Sometimes people living in places (like Manhattan) with a regularly spaced street grid will speak of long blocks and short blocks.
By 5 June 2011 astronauts had made over 159 EVAs to add components to the station, totaling more than 1,000 hours in space. [87] [88] Zarya and Unity, the first two modules of the ISS, pictured in May 2000. The foundation for the ISS was laid with the launch of the Russian-built Zarya module atop a Proton rocket on 20 November 1998.
It has been a valuable asset in supporting ground operations during conflicts such as Operation Iraqi Freedom. [231] The B-52 had the highest mission capable rate of the three types of heavy bombers operated by the USAF in the 2000–2001 period. The B-1 averaged a 53.7% ready rate, the B-2 Spirit achieved 30.3%, and the B-52 averaged 80.5%. [195]
Vendor interpretations differ. The rule refers to operation at both the target altitude and speed, but some receivers stop operating even when stationary. This has caused problems with some amateur radio balloon launches that regularly reach 30 km (100,000 feet). These limits only apply to units or components exported from the United States.
The type of guidance depends on the type of target. Ships, for example, may be detected via passive radar or active radar homing, which is less effective against multiple, small, fast-moving land targets. There is some cross-over between air-to-surface missiles and surface-to-surface missiles.
Meanwhile, a Ukrainian lieutenant, callsign "Alex", claimed that 300 Russian soldiers were captured in the "Kursk People's Republic" during two days, reportedly "conducted by a contingent of unidentified armed formations". He added that he hoped they would be handed over to his unit. [71] [72]
Within 30 minutes, local amounts of 50 mm (2.0 in) had fallen near Laporte and Livermore, with 50 mm (2.0 in) more falling near Loveland before the storm weakened around 8 pm. South of Fort Collins, new thunderstorm development began around 10 pm, which spread north through the city, dumping another 12 mm (0.47 in) of rain before dissipating ...
Four radio-collared females in Chitwan dispersed between 0 and 43.2 km (0.0 and 26.8 mi) and 10 males between 9.5 and 65.7 km (5.9 and 40.8 mi). [89] A subadult male lives as a transient in another male's home range until he is older and strong enough to challenge the resident male.
