Barring any unfortunate surprises, New Horizons is now studying the Pluto system up close with seven different science instruments, including cameras capable of picking out features on the dwarf planet's surface as small as the ponds in New York City's Central Park.

The spacecraft's observations will help researchers map the surfaces of Pluto and Charon in detail; characterize the two bodies' geology; and shed light on Pluto's wispy, dynamic atmosphere, among other things.

Researchers said they can't wait to get a look at the close-approach data. Their appetites have been whetted by observations gathered over the past few weeks showing that Pluto and Charon are complex worlds with surprisingly diverse surfaces.

For example, Pluto sports a polar ice cap and a huge, bright, heart-shaped feature, as well as a giant dark patch mission scientists have dubbed "the whale." Charon, for its part, is scored by craters and canyons, and harbors an enigmatic, 200-mile-wide (320 km) dark blotch at its north pole.

"The Pluto system is enchanting in its strangeness, its alien beauty," Stern said Monday (July 13) during a NASA news conference. "We are already seeing complex and nuanced surfaces that tell us of a history for these two bodies [Pluto and Charon] that is probably beyond our wildest dreams on the science team."

New Horizons is now operating in a nine-day-long "close encounter mode" that runs through Thursday (July 16). But don't expect a big data dump at the end of the week: It will take New Horizons up to 16 months to beam all its observations home. And team members won't even know if the flyby was successful until about 9 p.m. EDT tonight (0100 GMT Wednesday), when the probe's handlers expect to receive a check-in message. (New Horizons can't simultaneously gather observations and send information back to Earth.)

That status update will likely quell a bit of nervousness among the team members, because New Horizons is traveling so fast — 30,800 mph (49,570 km/h) relative to Pluto — that a collision with a piece of debris in the dwarf planet system as small as a grain of rice could be fatal.

Analyses suggest that dire outcome is extremely unlikely — but it's possible nonetheless.

"Formally, we're able to set model limits at around 1 in 10,000 [odds] that the spacecraft will be lost due to a debris strike," Stern said during Monday's news conference. "But we've also been very honest that we're flying into the unknown. This is the risk you take with all kinds of exploration.

ce Pembatasan kejutan disayangkan, New Horizons kini mempelajari sistem Pluto dekat dengan tujuh instrumen ilmu yang berbeda, termasuk kamera yang mampu memilih keluar fitur di permukaan planet kerdil sebagai kecil sebagai kolam di New York City Central Park. pengamatan pesawat ruang angkasa akan membantu peneliti memetakan permukaan Pluto dan Charon secara rinci; ciri geologi dua badan '; dan menjelaskan tipis, suasana dinamis Pluto, antara lain. Para peneliti mengatakan mereka tidak sabar untuk bisa melihat data close-pendekatan. Selera mereka telah merangsang oleh pengamatan yang dikumpulkan selama beberapa minggu terakhir menunjukkan bahwa Pluto dan Charon adalah dunia yang kompleks dengan permukaan mengejutkan beragam. Misalnya, Pluto olahraga topi es kutub dan, cerah, fitur berbentuk hati besar, serta ilmuwan misi Patch gelap raksasa telah dijuluki "ikan paus." Charon, untuk sebagian, yang dicetak oleh kawah dan lembah, dan pelabuhan yang penuh teka-teki, 200-mil-lebar (320 km) bercak gelap di kutub utara. "Sistem Pluto mempesona di keanehan, keindahan asing yang," Stern Senin (Juli 13) saat konferensi pers NASA. "Kami sudah melihat permukaan yang kompleks dan bernuansa yang memberitahu kita tentang sejarah untuk kedua badan [Pluto dan Charon] yang mungkin di luar mimpi terliar kami di tim sains." New Horizons kini beroperasi di sembilan hari panjang " Modus pertemuan dekat "yang berjalan sampai Kamis (16 Juli). Tapi jangan berharap data yang besar membuang pada akhir minggu ini: Ini akan mengambil New Horizons hingga 16 bulan ke balok semua pengamatan yang rumah. Dan anggota tim bahkan tidak akan tahu apakah terbang lintas yang berhasil sampai sekitar 9 pm EDT malam (0100 GMT Rabu), ketika penangan probe mengharapkan untuk menerima pesan check-in. (New Horizons tidak dapat secara bersamaan mengumpulkan pengamatan dan mengirimkan informasi kembali ke Bumi.) itu status update mungkin akan memadamkan sedikit gugup di antara anggota tim, karena New Horizons bepergian begitu cepat - 30.800 mph (49.570 km / h) relatif terhadap Pluto - yang tabrakan dengan sepotong puing-puing di sistem planet kerdil sekecil sebutir beras bisa berakibat fatal. [New Horizons Wears 'Bulletproof Vest' (Video)] Analisis menunjukkan bahwa hasil yang mengerikan sangat tidak mungkin - tapi itu mungkin tetap. "Secara formal, kami dapat menetapkan batas model pada sekitar 1 dari 10.000 [peluang] bahwa pesawat ruang angkasa akan hilang karena serangan puing-puing, "kata Stern selama konferensi pers hari Senin. "Tapi kita juga pernah sangat jujur ​​bahwa kita sedang terbang ke yang tidak diketahui. Ini adalah risiko yang Anda ambil dengan segala macam eksplorasi.
