▁There ▁is ▁therefore ▁some ▁risk ▁that ▁this ▁energy ▁can ▁be ▁released ▁prem ature ly ▁and ▁suddenly , ▁with ▁significant ▁effects . ▁When ▁a ▁D elta ▁II ▁ro cket ▁expl oded ▁ 1 3 ▁seconds ▁after ▁launch ▁on ▁January ▁ 1 7 , ▁ 1 9 9 7 , ▁there ▁were ▁reports ▁of ▁store ▁windows ▁ ▁away ▁being ▁broken ▁by ▁the ▁bl ast . ▁ ▁Space ▁is ▁a ▁fairly ▁predict able ▁environment , ▁but ▁there ▁are ▁still ▁ris ks ▁of ▁accident al ▁de press ur ization ▁and ▁the ▁potential ▁failure ▁of ▁equipment , ▁some ▁of ▁which ▁may ▁be ▁very ▁newly ▁developed . ▁ ▁In ▁ 2 0 0 4 ▁the ▁International ▁Association ▁for ▁the ▁Ad van cement ▁of ▁Space ▁Saf ety ▁was ▁established ▁in ▁the ▁Netherlands ▁to ▁further ▁international ▁co operation ▁and ▁scientific ▁adv ancement ▁in ▁space ▁systems ▁safety . ▁ ▁We ight less ness ▁▁ ▁In ▁a ▁micro gravity ▁environment ▁such ▁as ▁that ▁provided ▁by ▁a ▁space craft ▁in ▁orbit ▁around ▁the ▁Earth , ▁humans ▁experience ▁a ▁sense ▁of ▁" weight less ness ." ▁Short - term ▁expos ure ▁to ▁micro gravity ▁causes ▁space ▁adaptation ▁synd rome , ▁a ▁self - lim iting ▁n ause a ▁caused ▁by ▁der ang ement ▁of ▁the ▁vest ib ular ▁system . ▁Long - term ▁expos ure ▁causes ▁multiple ▁health ▁issues . ▁The ▁most ▁significant ▁is ▁b one ▁loss , ▁some ▁of ▁which ▁is ▁permanent , ▁but ▁micro gravity ▁also ▁leads ▁to ▁significant ▁de condition ing ▁of ▁mus cular ▁and ▁card i ov asc ular ▁t issues
